Title: Vacuum valve
Inventor: OKUTOMI ISAO
IPC: C22C5/06
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To maintain an excellent large-current interrupting characteristic by combining composition-gradient contacts whose material compositions on the contact surfaces are changed as specified and a magnetic flux density distribution inclination means for changing the magnetic flux density on the contact surfaces as specified. SOLUTION: Material compositions on the surfaces of a pair of contacts arranged inside a vacuum container in such a way as to freely touch and leave each other undergo gradient changes in concentric circles on a certain radius line. A magnetic flux density distribution inclination means is provided for causing gradient changes of magnetic flux intensity in concentric circles on the radius line on the contact surfaces. The combined effect of the contacts and the means causes an arc produced when a large current is interrupted to be readily moved and diffused over the contact surfaces having the composition gradients, without stopping and concentrating on portions where arc voltages are low; i.e., a critical current value at which an anode spot is formed is increased so that an excellent large-current interrupting characteristic can be maintained.

Abstract: PURPOSE:To make an oxide film around an emitter electrode thick, and make the distance between collector-emitter apertures as small as possible, by forming an emitter electrode before a polycrystalline silicon film is activated, and performing etching in the manner in which a residual film of the polycrystalline silicon film is formed around the emitter electrode. CONSTITUTION:An emitter electrode 18 is formed before a polycrystalline silicon film 24 is activated. A silicon oxide film formed by vapor growth and a polycrystalline silicon oxide film are eliminated, and at the top part of the emitter electrode 18, the polycrystalline silicon oxide film 12 and a nitride silicon film 13 only are left, which are subjected to thermal oxidation. Thus, a new polycrystalline silicon oxide film 26 is grown on the side surface of the emitter electrode 18 and the whole surface of the exposed polycrystalline silicon film 24. Since two layers of insulating film are formed on the whole surface of the emitter electrode 18 and the recessed inner surface around the electrode, an polycrystalline silicon oxide film 26 on the polycrystalline silicon film 24 are selectively eliminated, and then the polycrystalline silicon film 24 is activated. At the same time, a high concentration region 16 to lead out the collector is formed just under a collector aperture part 8.

Abstract: PURPOSE:To eliminate the necessity for using a vacuum gage in the method accurately detecting a pressure and a flow quantity being based on a control condition of a motor by grasping a control characteristic value suited for a load condition and detecting the pressure or the flow quantity being based on this control characteristic value. CONSTITUTION:A control is performed on the assumption that a load condition of a rotary blade in a turbo molecular pump is monitored applying a feedback and rotating the rotary blade always in a fixed speed so as to hold compression ratio of the turbo molecular pump and its exhaust speed to a fixed value. From the fact that a load of the rotary blade is an amount of gas, a flow quantity is detected by using a control parameter of a motor driving the rotary blade. While from the fact that a pressure P, exhaust speed S and a flow quantity Q obtain a relation where P=Q/S, the pressure P and the flow quantity Q can be simultaneously detected on condition that the speed S is in a fixed value.

Abstract: PROBLEM TO BE SOLVED: To provide a cover for the insulation/waterproofing of a cable connecting portion, wherein the tubes made by extrusion moldings can be used and its waterproof performance can be amply secured. SOLUTION: A cable connecting portion is inserted into the armoring tube 1, while supporting in a diameter extending way inner tubes 2a, 2b and both the end portions of an armoring tube 1 by diameter extending support-members 3. Then, the inner tubes 2a, 2b and the armoring tube 1 shrink themselves respectively to mount them on the cable connecting portion scraping and removing the diameter extending support- members 3. Since the inner tubes 2a, 2b have respectively their inner diameters corresponding to the outer diameters of the insulators of cables 4, 5 to be connected with each other and respectively have their outer diameters slightly larger than the inner diameter of the armoring tube 1, the interfaces among the inner tubes 2a, 2b, the cables 4, 5, and the armoring tube 1 are adhered to each other to ensure their waterproof property.  Also, when the inner diameter of the armoring tube 1 is made slightly larger than the outer diameter of a conductor connecting metal-fitting 6, the armoring tube 1 is prevented from damaging, even if these are burrs on the conductor connecting metal-fitting 6.
